“…In the investigation, the values of n are within the range of 0.85 to 0.93, implying the inhomogeneity or roughness of the carbon steel surface, which causes the slight deviation from an ideal capacitance. 35,48 These results again prove that SbW 9 -TM-SnR/BiW 9 -TM-SnR possess good corrosion inhibition behavior for 20 # carbon steel in 0.5 M HCl solution.…”

“…It is noted that the IE w values of SbW 9 -TM-SnR and BiW 9 -TM-SnR are slightly reduced in 2.0 M HCl compared to those in 1.0 M HCl, which is presumed to be because (i) a high concentration of Cl − penetrates the anticorrosive film and causes repitting corrosion and (ii) the corrosion film dissolves or decomposes. 35 In addition, the corrosion inhibition performance of SbW 9 -TM-SnR is slightly better than that of BiW 9 -TM-SnR. It can also be seen from .7% in 0.5, 1.0, and 2.0 M HCl solutions, respectively, which shows that the organotin component plays an important role in the corrosion protection of carbon steel although its content in the POM system is low.…”

“…The above results show that these POM-based inhibitors have good corrosion inhibition performance for carbon steel in acidic solutions, and the type of TM component has little effect on the corrosion inhibition property.

The development of acid-resistant and efficient corrosion inhibitors is of great significance for metal protection in many industrial processes. In this work, eight cases of sandwichtype polyoxometalate (POM)-based inorganic−organic hybrids, namely, carboxyethyltin and transition metal (TM) cofunctionalized tungstoantimonates and tungstobismuthates, formulated as Na x K 10−x [(SnR) 2 (TM(H 2 O) 3 ) 2 (B-β-SbW 9 O 33 ) 2 ]•mH 2 O and Na y K 10−y [(SnR) 2 (TM(H 2 O) 3 ) 2 (B-β-BiW 9 O 33 ) 2 ]•nH 2 O (abbreviated as SbW 9 -TM-SnR and BiW 9 -TM-SnR;

“…In addition, with the extension of immersion time, it was found that the charge transfer resistance R t of all samples decreased in varying degrees. It means that the corrosion resistance of the coating decreases gradually [37][38][39]. The impedance modulus |Z| of the lowest frequency (0.01 HZ) in the Bode diagram can be used as an indicator of the impermeability of the coating.…”

In order to improve the corrosion resistance of zinc-rich epoxy coatings and reduce the amount of zinc used, first, graphene oxide (GO) was modified by sulfonated multiwall carbon nanotubes (SMWCNTs) to obtain the modified graphene oxide (SM-GO). The samples were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and Raman spectroscopy. Then, four kinds of coatings were prepared, namely pure zinc-rich coating (0-ZRC), graphene oxide-based zinc-rich coating (GO-ZRC), sulfonated multiwall carbon nanotube-based zinc-rich coating (SM-ZRC) and SM-GO-based zinc-rich coating (SG-ZRC). The corrosion resistance of the above coatings was studied by open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), a salt spray test, 3D confocal microscope, and electron scanning electron microscope (SEM). The results indicate that GO is successfully non-covalently modified by SMWCNTs, of which the interlayer spacing increases and dispersion is improved. The order of the corrosion resistance is GO-ZRC > SG-ZRC > SM-ZRC > 0-ZRC. The addition of GO, SMWCNTs, and SM-GO increases the shielding effect and increases the electrical connection between Zn particles and metal substrates, which improves the corrosion resistance. However, SMWCNTs and SM-GO also strengthen the galvanic corrosion, which decreases the corrosion resistance to some extent.

In this work, the aqueous Lawsonia inermis extract (LI) is investigated as an economic and green deterioration inhibitive formula for steel alloy 4130 in 3.5 wt.% NaCl solutions. The water-based extraction process is considered as one of the cheapest techniques for preparation of active ingredients of natural products. These ingredients play an important role in corrosion mitigation of steel alloy 4130 in saline media. This extract was subjected to three different parameters: inhibitor concentration, rotation speed, and temperature in 3.5 wt.% NaCl solutions. The electrochemical techniques are used to perceive the corrosion behavior, and the obtained results were dedicated to theoretical explorations to assess the features of corrosion inhibition and the adsorption over the steel substrate in 3.5 wt.% NaCl solutions. Affording to the electrochemical techniques of LI showed very promising results against corrosion depending on the inhibitor concentrations. The inhibition efficiency of LI was additionally appraised at three diverse temperatures, and the results disclosed that the inhibition efficiency is decreased. Additionally, the theoretical aspects illuminated that the main active ingredients of LI have a proclivity to coagulate on the steel substrates allowing these areas to paradigm a protecting layer on the steel surfaces. This behavior is in provision of investigational results. Statistical studies were used to examine the consequence of chief constraints (i.e., inhibitor concentration, temperature, and rotation speed) on the inhibition efficiency and the rate of corrosion of steel alloy 4130. The inhibitive effect of LI in contradiction of the corrosion of steel alloy 4130 surfaces is considered by resources of DFT/6-31G(d) calculations. The quantum chemical parameters interrelated to the inhibition efficiency are considered.
